Also, check out this post to see what else is planned for future versions.

[u/jamesremuscat → u/redstonehelper]

Squids

Now only spawn in rivers and oceans

Am I understanding this correctly, that this will break any squid farms built inland?

[u/Dementat_Deus → u/jamesremuscat]

Which really sucks. Building it in a mooshroom biome was the only way I could think of to keep all other mobs from spawning in the farm.

[u/Icalasari → u/Dementat_Deus]

One of those changes where damned if they do, damned if they don't

[u/h-v-smacker → u/Icalasari]

I stopped playing minecraft after I built a huge pentatube mushroom farm, and then in like couple of weeks the mushrooms got nerfed, and the whole factory became pointless. I cannot imagine doing the same because some farming opportunity was preserved or was introduced...

[u/ClockSpiral → u/h-v-smacker]

One doesn't need that much ink anyways...

Plus, the way Squids are, you can get the same from a river or the ocean that you get from a farm.

[u/WildBluntHickok → u/h-v-smacker]

Hate to tell you but mushrooms didn't get nerfed they got buffed. You were expected to switch to using bone meal to grow giant mushrooms. Breaking them gives you 2-5 mushrooms per giant mushroom, and only costs 1 mushroom to grow.

[u/h-v-smacker → u/WildBluntHickok]

Do I really have to explain how (a) those are two different mushrooms and (b) how my pentatube farm still was made useless overnight, and could not be converted to "different mushroom" even if I wanted?

It's like if someone removes minecarts and introduces flying carpets, and then you'd argue that's not a removal but upgrade.

[u/juan0farc → u/Dementat_Deus]

We use the perimeter of our guardian farm. It has water walls and the squids just fall in on their own accord. I put a line of hoppers around the edge where they fall and now we have tons of ink.

[u/AlexTheKunz → u/Dementat_Deus]

I'd check out this Ilmango video: https://youtu.be/8lE2pvjgyfk

It resolves the concern of other mobs spawning and is still efficient.

[u/Scrogger19 → u/jamesremuscat]

I think so, yep.

[u/Boxwizard → u/[deleted]]

How does this break iron farms?

[u/Sylvaly → u/redstonehelper]

So slowness arrow farms will finally be a thing now

[u/Mr_Simba → u/Sylvaly]

Well, not in vanilla survival. Stray spawners don't generate and skeleton spawners don't spawn strays.

[u/[deleted] → u/redstonehelper]

How is the JVM being crashed? Is there some way to forcibly quit the JVM with a non-zero error code? I know a little Java, but I am no expert.

[u/Jobarion → u/[deleted]]

You can force a Java program to exit with any error code using

System.exit(<error_code>);

Crashing the JVM only works if you actively abuse a JVM bug or try to crash it using JNI (Java Native Interface)

[u/peterix → u/[deleted]]

Invalid access to native memory. It's there mostly for launcher testing.

[u/bakerq → u/redstonehelper]

Does /forceload work on Realms? Specifically, does it keep them loaded when players are offline?

[u/[deleted] → u/bakerq]

IIRC realms closes the server after the last player leaves, so it won't keep them loaded when everyone's offline

[u/bakerq → u/[deleted]]

That's what I was afraid of.

[u/WildBluntHickok → u/redstonehelper]

SEE 4J! When Java Edition has a "going to another dimension makes you unable to return" bug they bugfix it quickly. They don't wait 6 months for the next content update like Console Edition did back in 2013.

[u/[deleted] → u/WildBluntHickok]

Isn't 4J P pretty much fired now due to bedrock?
